Thank You for reply. Update is: oscillating voltages on bq ic could be normal. Found on other forum voltages but not sure for 100%....Leave a comment:

Thank You for response. Yes i will do that. My next idea is also to take another laptop (diffrent company) but with the same BQ ic and check pin voltages also....Leave a comment:

When laptop is connect to power, under thermal camera bq ic get hot, pulsuating. power supply shows 7 to 16mA. Also I've noticed strange voltage on BATFET gate - from 6.5 to 8volts and changing. There should be voltage from BQ ic connected by 4kohm resistor. But i dont know why this gate voltage changing....Leave a comment:

This is third BQ ic tested and still the same...Leave a comment:

Asus f15 Fa506 no screen BQ24780s
Hi to All. Problem with laptop is no screen after power up. I have changes bios software many times and there is new bios chip also. Laptop still coming on with no picture.
Every power line is present.
I have noticed that in off Mode laptop take 7mA and then 10 to 16mA and coming back. Was interesting what is taking this current. Bq24780 is flickering. I check there is 2.6v, 6v, 18v present. Baterry is charging. What could be problem then? When i remove bios chip laptop takes 7mA only. Could be bios issue still or next step is kbc?... -

Today i spotted that there is Mark after connecting probe to cpu coil and copper from radiator. I have short on drain source Qn3110 nmos. Removed them and they are good. But there is still short beetween drain and source. Why? I removed three coils and drain to source short is gone. It is weird becouse i have 6ohm when cold board on those coils. I have put 0.7v to processor and it take 200mA, no hot spots on thermal camera on processor. After that I took cold spray and cpu is changing resistance. Im confused. CAN You help?...Leave a comment:

Im doing it with ch341a(i know), but i modified it couse was error on 25Q winbound chips. Bios is not empty (at third time it read succesfully). Inside this bios is clean bios from Asus page under my model. Bios was cut 800 on begining. I have one bios from internet but little diffrent device and number on winbound ic little diffrent. Im trying to cut and paste only serial number in it which is on laptop cover. But there is more than fifty places with serial number. Maybe this will work?...Leave a comment:
